UPDATE - Firemen hurt in Frankfurt chemical plant blaze

At least eight firefighters were taken to hospital with eye problems from hydrochloric acid released in the blaze. Residents in the Frankfurt suburb of Griesheim were warned by sirens and over the radio to keep their windows closed. Police said initially that a blast caused the fire, but a company spokesman said later the cause of the blaze was not clear. No Clariant employees were hurt, the spokesman said. The fire, which was extinguished after about two hours, took place in a section of the Clariant plant where a component of an insecticide was produced. REUTERS NEWS SERVICE
